I don't understand why public is considered "lack a reasonable expectation of privacy". In Switzerland this only applies if you are in public at a large gathering or event where the use of cameras etc. is expected. In any other situation in public, if you single out a specific person (even if their face is not visible but they are identifiable by clothing/tattoo or vehicle registration etc.) in a video you are violat…
I think there's a distinction between being recorded in the first place, and what the recording might be used for in the future. I think it's OK to permit a recording to take place in a public place without explicit consent, but still require consent to use that recording in (for example) publishing it where someone is a feature in that publication (as opposed to someone who happens to be in the background and remain…
The truth is that we live in a _very_ different world than when these laws were set up. The idea of reasonable expectation was very different because you wouldn't reasonably expect to walk down the street being recorded since cameras were bulky, expensive, and uncommon. Now every single person has one in their pockets, most businesses are recording you, you're being recorded from airplanes in the sky[0], and not too long from now satellites will (governments already have this capacity but commercial is near there[1]). You didn't have a reasonable expectation for the person standing next to you to be capable of recording your conversation. It was possible for them to wear "a wire" but the likelihood was very low. Likelihood being low is equivalent to "reasonable expectation." The reasonable expectation of not being recorded didn't come from being hidden or out of sight, it came from the fact that the technology either didn't exist or wasn't prevalent. Not it is ubiquitous. And despite it seeming so normal, most of this change happened in the last 20 years.
But we're getting to the next paradigm shift, which makes all the above even more pervasive. ML/AI. I say this as someone that works in ML/AI and loves the field with a passion (you'll see me discuss it a lot here). But the technology also has downsides (commonly referred to as "malicious AI"). It isn't AGI, it is the ML that already exists. We can identify faces in a crowd and track them across different videos. We can take that 2 pixel person, segment it, and track it (done manually in the radiolab referenced in [0]). We can identify a person by the way that they walk (gait recognition[2]). We can track you by your wifi and bluetooth signal within a building. And so much more. This technology has supercharged the surveillance ecosystem (not somewhere I work in, obviously) and you bet it is being used by countries who don't have the best human rights records (let's not make this a (who's) dick (is the ugliest) measuring contest). Things have changed well beyond what we could have reasonably assumed 20 years ago, even 10. Now, it is not unreasonable to believe that such systems will also perform on the web and that your text is likely identified by you patterns, not just your fingerprint.
And this is really it. This stuff is so prolific that we've erased our memory of the past and re-framed this "normal" behavior as applicable to the past and try to justify it. 20 years ago you could walk down the street and reasonably assume that you would not show up on any single camera. Moreso, you could reasonably assume that if you did, you wouldn't show up on many. That that video was unlikely to make it to the internet. And that that video would likely be low grade and unable to identify you. These are all different things, but combined they sum to the expectation that there would not be a record of your movement contingent upon your ability to be identified (same applies to the internet and our chat forums in a similar line of reasoning). __STOP JUSTIFYING "REASONABLE EXPECTATION"__ without recognizing that the ecosystem has rapidly changed and is significantly different from when those laws were written. You are not making a strong argument but rather just reinforcing the surveillance paranoia (as in, people who are paranoid[3] about surveillance will increase said paranoia due to increased relaxation coupled with "nothing to hide" mentality that enables said surveillance).
=== TLDR ===
Just because you were in public didn't mean you'd reasonably expect to be recorded. The ecosystem has rapidly changed and we need to recognize this. 10-20 years ago you didn't have a reasonable expectation to be recorded (video or audio) in public as {government,corporate,civilian} recording capabilities were far less.

[3] Paranoia is a bad word because it implies an unjustified or unwarranted mistrust. I think we can all agree that to some degree there is justification. The disagreement is just how much. But I am using the term because it is more prolific and I think the context is appropriate to draw upon the dichotomy in how what was once thought to be tinfoil hat claims become reality: see Snowden. 50 years ago a person that claimed our every move would be tracked -- in the real world and virtual -- would have been called crazy. It was even the stuff of dystopian science fiction. Now we call that a Thursday.
